Grip for automobile-tires.



PATRICK SMITH, OF FQRESTHILL, CALIFORNIA..

GRIP FOR AUTOMOBIL E-TIRES.

i citizen ot the United States, and a resident ot Foresthill, in the conntyof Placer and State ot California, have invented a new and Improved Grip for Automobile-Tires, of which the following is a full, clear, and exact description. i

The prime object of my invention is to provide an attachment that may be applied to the shoes of automobile tires to present etfective gripping members and of a characvter to accommodate itself to the flexure of the tire.

More specific objects ot' the invention are to provide an attachment of the indicated character composed otsections made up of parts that may be readily assembled; and to provide an attachment to be durable and not liable to become broken or disarranged.

The invention will be particularly explained in the specific description following.

Reference is to be had to the accompanying drawings vforming a part of this specification in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a partly sectional side elevation of a portion ot' a wheel and tire showing my attaclnnent applied thereto;

Fig. 2 is a plan view ot a section of a tire having my invention applied thereto;

Fig. 3 is a cross section on the line 3 3, Fig. 1.

In constructing an attachment in accordance with my linvention, a series ot transverse gripping sections are provided each composed ot separate curved members 10, the curvature corresponding to the curve of the tire shoe to which the attachment is to be applied. Each member 10 ot a gripping section is formed with a beveled rib 11, said ribs alining when the members are assembled.

rilhe members 10 of each section are fiexibly connected through the medium of a transverse cable l2 which preferably is of wire, said cable being accommodated in registering bores 18 in the respective inembers 10, the bores of given section being in register. Preferably, the bore 13 is formed in each section at the base of the rib 11.

On each cable 12 at one end is perma- Specifcation of Letters Patent.

Application led 0otober`20, 1916. Serial No. 126,709.

nently secured a sleeve or head 14 of greater diameter than the bore 13 and adapted to abut against the end of the adjacent rib 11. At the opposite side of the tire a clamp 15 is secured to the end of the cable 12 to abut against the end of the adjacent rib 11. The ribs 1l on the side sections. 10 terminate short of the inner ends of said sections whereby to produce' projecting flanges 16 which are overlapped by the elements 14, 15. The clamp 15 is composed of two sides adapted at their outer ends to receive between them, the adjacent end of the cable 12 to which the clamp sections are secured by a bolt 17. On the sleeve or head 14 at the inner end, a ring 18 is rigidly secured and a ring 19 hasamember thereon extending between the sections of the clamp l5 at the inner end so that the bolt 17 will effectively clamp both the cable and the said ring 19.

rlhe respective rings 19 are connected byv chain sections 20 that extend annular-ly about the tire. Also, a cord or equivalent iexible element 21 is laced alternately through the rings 18, 19 and beneath the telly B.

Adjacent transverse gripping sections are connected and spacedrby peripherally arranged links 22 having longitudinal gripping ribs 23 thereon, which preferably are beveled like the ribs 11. The ends of the links 22 are forked and receive bolts 24, or the like, bolts being shown in the illustrated example. and provided with nuts 25, the bolts passing also through flanges 26 on the opposite sides of the central members 10. The provision of the clamps 15 permits of the ready detachment of the adjacent end of the cable 12 so thatthe latter may be drawn through the members 10 for repair or the like.

By the described construction effective gripping members are provided on the tire and the elements, it will be observed are of strong and simple construction that may be readily assembled.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

A grip attachment for tires comprising spaced transverse curved sections, each section being composed of separate side memhers and an intermediate member, said members having registering bores and following the curvature of the members, a flexible cable extending through the bores of the respective members in each section, 'a sleeve rigidlv secured to one end of the cable and abuttngfagainst the end of the adjacent
